0.1.0a2

More than a year after starting this project I can finally present a working version.

I started with a LibCST PoC which was very slow and migrated to rust soon after that. Then I did the mistake to use the abandonded rustpython-parser AST implementation instead the ruff implementation.
So I did a lot of refactoring, testing and experimenting to get to this version which is able to bundle and treeshake... flay itself. So now it is time for me to test this with other projects.

There is still a lot todo. I think there can still be done a lot performance-wise and currently not a lot of code is stripped away because of the many edge cases and hacks in python's ecosystem which make it hard to determine if code is actually used or not. Stay tuned!
